Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0026] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0027] As shown in FIG1 , a top-inlet stove burner includes a cup body 1, a nozzle 3, a fire distributor seat 2 and a fire cover 4.

[0028] The cup body 1 includes an annular seat plate 11 surrounding an opening on the cup body 1 and a longitudinal air inlet and outlet seat 12. The longitudinal air inlet and outlet seat 12 intersects with the annular seat plate 11 and intersects with the cup body 1 at its upper end. The air outlet end of the longitudinal air inlet and outlet seat 12 extends into the cup body 1. A nozzle mounting hole 121 is provided at the upper portion of one side of the longitudinal air inlet and outlet seat 12, and an air inlet port 122 is provided at the lower end.

[0029] The ignition distributor base 2 includes an upper-opening combustion chamber 21, a U-shaped air guide channel 22, an axial gas channel 23, an ejector tube 24, and a front upper air chamber 25. The front upper air chamber 25, the ejector tube 24, and the U-shaped air guide channel 23 are arranged in sequence from front to back. Two axial gas channels are arranged on the left and right. Both ends of the U-shaped air guide channel 22 are connected to the axial gas channel 23, and the axial gas channel is connected to the combustion chamber 21. A combustion groove is provided on the wall plate of the combustion chamber 21.

[0030] Fire cover 4 is in the shape of a circular plate;

[0031] The nozzle 3 is fixed to the nozzle hole 121 of the longitudinal air inlet and outlet seat 12. The rear U-shaped air guide channel 22 is embedded in the cup body 1, and the upper end of the cup body 1 supports the shoulder 221 of the U-shaped air guide channel 22. The front upper air cavity 25 and the upper opening at the front end of the cup body 1 are opposite each other. The air inlet and outlet seat is inserted into the front upper air cavity 25 to support the ignition distributor seat 2. The nozzle 3 corresponds to the ejector tube 24. The lower end of the front upper air cavity 25 and the front end of the upper opening of the cup body 1 form the primary air channel. The primary air channel is located above the cooktop and opposite the nozzle 3. Air flow is smooth, providing sufficient primary air.

[0032] As a further improvement of the present invention, the two side walls of the inner cavity of the cup body 1 are provided with limit plates 13; the ends of the U-shaped air guide channel 22 cooperate with the limit plates 13 to limit the position. With this structure, the ignition distributor seat 2 can be prevented from moving left and right and front and back relative to the cup body.

[0033] The U-shaped air guide channel 22 includes a rear arc portion 222, a left air guide portion 223 and a right air guide portion 224.

[0034] The ejector tube 24 communicates with the rear curved portion 22, and the left and right air guide sections 223 and 224 each communicate with an axial gas passage 23. Gas entering the ejector tube 24 and air are premixed in the rear curved portion 22. The gas is then split by the left and right air guide sections 223 and 224 before entering the combustion chamber 21 through the axial gas passage 23. This ensures that the gas and air are evenly distributed and thoroughly mixed.

[0035] The lower part of the air inlet end of the ejector tube 24 extends into the cup body 1, and the upper part extends into the front upper air cavity 25. The front upper air cavity 25 and the cup body 1 play a role in stabilizing flow, and the primary air channel corresponds to the air inlet end of the ejector tube.

[0036] As a further improvement of the present invention: the cup body 1 is further provided with a fixed base plate 14, and the fixed base plate 14 is provided with an ignition needle fixing hole 141 and a sensor needle fixing hole 142;

[0037] The combustion chamber 21 of the ignition distributor seat 2 is provided with a receiving chamber 26, and the bottom plate of the receiving chamber 26 is provided with an ignition pin hole 261;

[0038] The ignition needle hole 261 is opposite to the ignition needle fixing hole 141 , and the ignition needle and the ignition needle hole 261 are detachably matched, and the ignition needle also plays a role in fixing the ignition distributor seat 2 .

[0039] The volume of the inner cavity of the ejector tube 24 gradually decreases from the air inlet end to the air outlet end.

[0040] As a further improvement of the present invention, the axis of the nozzle hole 121 has an elevation angle α compared to the horizontal plane in the cup body 1. With this design, it is more convenient to process the nozzle hole 121 and install the nozzle 3.

[0041] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
